The connector for the EIA-530 (EIA-422) cable is a DB25 Female.

Note: EIA-232 and one of the V.35 cabling options use a DB25 female connector, and can be easily confused. The PCI Sync adapters are capable of determining the cable type attached to a port, and each OS has a version of the Port Assist Viewer that can be used to verify the cable type in place. The SYNC/570i UIB cables are plainly labeled on the DB25 end of the cable.
